PICTURES: Wow! Wendy Williams Poses Nude for PETA

Hot talk? Hot bod!

The outspoken Wendy Williams lets her figure do most of the talking in a startling new campaign for PETA. The latest celebrity model to bare her body for the organization's iconic "I'd Rather Go Naked Than Wear Fur" campaign.

Launching a new national campaign on Wednesday Nov. 28, the talk show host, 48, was on hand to present her huge billboard in NYC's Times Square; in the shots, Williams wears nothing at all, with her toned figure concealed only by her long, flowing hair.

"We should all try to be comfortable in our own skin and let the animals keep theirs," said Williams in a statem ent. Williams used to wear real mink and fox, but changed her mind when she learned how animals are brutalized for their furs.

This holiday season, Williams will also encourage her fans to donate used fur coats to PETA -- with the aim of donating the coats to the homeless and victims of Hurricane Sandy.

Williams joins the ranks of other stars who've graced PETA's "Go Naked" campaign, including Eva Mendes, Christy Turlington, Taraji P. Henson and others.

Katy Perry: I Feel Fat Without Spanx!

Katy Perry has been called "The First Lady of Hot" by Maxim, but she doesn't always feel worthy of the title.

Us Weekly caught up with the "Part of Me" singer at the Nov. 28 UNICEF Snowflake Ball in New York City, where she and other celebs including Selena Gomez, Uma Thurman, Tony Bennett and Kelly Ripa walked the blue carpet and helped raise money for UNICEF'S lifesaving children's programs.

The pop star, 28, was stunning in a tight, floor-length, semi-sheer navy Naeem Khan dress with a matching cape, Guiseppi Zanotti heels, a Judith Leiber clutch, and Lorraine Schwartz jewels -- but she admitted she didn't feel as good as others thought she looked.

"I feel like my [fat] is sticking out so bad right now," she confided in Us at the bash. "I almost always wear [Spanx], but not tonight, and I feel it pushing out, making me look fat."

"I like to say I run on the elliptical for 30 minutes watching CNN, but I don't do it often enough," she added. "So I'm just like, 'Oh, I guess I'm not fitting into this Lanvin dress for these couple of months.'"

Perry may not always love her curves, but plenty of other people do -- including on-again boyfriend John Mayer, who recently accompanied the singer on a romantic tour of the Old Mission in her hometown of Santa Barbara, Calif. The two have also been spotted packing on the PDA at several Hollywood hot spots.

"They were in their own world," a guest at Perry's October birthday bash told Us of the couple, who reunited in September after briefly separating in August. "She didn't even talk to her friends much. It was just her and John. She's obsessed with him."

Gaunt Matthew McConaughey: "I'm Not Being Starved" for Movie Role

Matthew McConaughey -- or what's left of him -- is perfectly healthy, thank you very much.

The 42-year-old actor is currently filming The Dallas Buyer's Club, in which he plays Ron Woodruff, a real-life drug addict in the 1980s who contracted HIV and became one of the first-ever AIDS activists. To get into character for the role, McConaughey has been dieting down his muscular frame to skin and bones.

"I'm a little more streamlined," he told the Daily Beast on Nov. 27 of his nearly 40-pound weight loss.

That's an understatement. The usually buff Magic Mike star -- now just 143 pounds -- has set the Internet abuzz with worry in recent months thanks to his gaunt, frail appearance. But he insists there's no cause for concern.

"I feel fine. I really do," he told the site. "I got the means to lose the weight in a really healthy way. I'm eating fresh fish. I'm just eating small amounts. I'm not being st arved...I'm taking care of myself."

"I've been checked. My levels are fine. I'm as healthy as can be," he added. "The real health challenge is when you put [the weight] back on...You can't just start eating cheeseburgers and ice cream. Your body will go into shock, and it just won't work."

Learning about how his body does work has been something of a "spiritual journey" for the soon-to-be father-of-three. (McConaughey and wife Camila Alves have two kids, Levi, 4, and Vida, 2, with a third on the way: The pregnant model, 30, is currently in her third trimester.)

"It's really been enlightening to understand my anatomy," he said. "I don't have the leverage I used to. I have body soreness."

That said, the physical changes are just one part of the actor's overall transformation.

"I'm playing a guy who was sick and would have loved to have been healthier but wasn't," he told Us Weekly in August. "For me, it's more of a mental thing than a physical thing."
